I’m happy with the rebuilt 765R4.
I wanted to “Make Automatics Great Again”. So far it’s a home run.

Have the transmission built with a 4th gear pressure switch in the valve body, then just wire up the torque converter solenoid to that switch, it will only go into lockup in 4th gear, nothing else needs to be switched, this can also be done after the transmission is built all you have to do is tap the 4th gear servo cover and put a switch in it.Hi Guys, I’m swapping 700r4 for TH400 and getting ready to order the torque converter lock-up circuit. Do I need the dual brake switch to drop out the lock-up? If so, what switch is recommended? Also… could use some advice on how to configure the TV cable and shift linkage. I’m in a 1986 M998 that I’m converting from stock. Thanks!

EDIT, the 4th gear servo cover is the round thing on the right side of the transmission.

it requires some modification, specifically dragging a round hole to oval to make it fit/mount properly.Bowtie overdrives has a tv cable that will work.
I'm wrapping up my 700r4 conversion and am struggling to come up with an easy adapter for the shifter linkage. Do you happen to have any photos of your linkage that you built? Would appreciate your advice. I really don't want to pay $$$ for the 4 speed shifter... at least not right now. ThanksUpdate: the 700R4 is installed but not yet complete. The shop I used did most of the work. I need to finish shifter linkage, and run 12v signal to trans for brake switch. I did drive it about 50 miles on the interstate manually shifting. My recorded top speed was 75mph. It will run 70mph but struggles on inclines. I'll have more info when the small bits sorted. I do not have a tachometer.
